Patent CA-2127157-A1 (CA)
Inventor: MORI TAKASHI
IPC: H02J3/18
Filed: 1994-06-30
Abstract: According to the present invention, there is pro-vided a self-commutated static var compensator for sta-bilizing a power system by controlling an output of a self-commutated converter for receiving/supplying power from/to the power system.  A constant system voltage maintaining controller calculates a first target value signal of the reactive current in accordance with a dif-ference between a reference voltage and a voltage detected by a voltage detector, and a reactive current controller generates a second target value signal of the reactive current in accordance with a difference between the first target value signal of the reactive current and a detected current.  A converter controller applies a gate driving pulse to the self-commutated converter in response to the second target value signal of the reac-tive current and second target value signal of the active current.  A loss reduction circuit stops the gate driving pulse corresponding to the second target value of the reactive current from being supplied to the gate of the self-commutated converter when reactive power output from the self-commutated converter is close to zero.

Title: Improved batting practice device using extensible member
Inventor: CIPRIANO RONALD J
IPC: A63B69/00
Filed: 1994-03-21
Abstract: A batting practice device comprising a relatively stiff, elongate tubular member (12) with a handle (14) located on one end and the other end being open and containing in its interior an elongate ball supporting member (18) slidably disposed in a telescopic manner in the interior of the tubular member (12), a ball (28) tightly disposed on the outer end of the ball supporting member (18). The ball supporting member (18) is readily movable between a compacted position in which most of its length is contained in the interior of the tubular member (12), and an extended position in which a relatively small amount of the length remains inside the tubular member. To assort the ball supporting member remaining in the extended position during use, a locking collar (44) is used, which can also be used to retain the ball supporting member in the compacted position. To prevent the ball supporting member from becoming separated during use, a rigid member (60) is extended through the length of the ball supporting member.

Title: Corrosion monitoring tool
Inventor: WATERMAN DAVID K
IPC: E21B47/12
Filed: 1995-02-16
Abstract: A tool for monitoring corrosion levels within a wellbore particularly suited for remote monitoring over extended periods.      The monitoring tool utilizes a thin wall electrical resistance type corrosion sensor to determine rate of metal loss within the wellbore. The corrosion sensor is preferably made of the same material as the production tubing or drill pipe of the well and is positioned to allows the fluid within the wellbore to flow over the sensor at the same rate as the fluid flows over the tubing. A reference element is incorporated into the corrosion sensor to provide primary temperature compensation. A temperature sensor provides temperature data and allows for secondary temperature compensation for the corrosion sensor. A central processing unit reads and stores the data from the three sensors into solid state memory. The probe records data at programmable time intervals.      Upon retrieval of the probe from the wellbore, the probe may be connected to a computer for downloading of the raw data and subsequent analysis.

Patent CA-2161723-A1 (CA)
Inventor: BERTOCCI GUIDO
IPC: H04M1/72508
Filed: 1995-10-30
Abstract: A cordless telephone system achieves synchronism for each one of multiple portable units to the same communication  channel for communicating with a common base unit. The cordless system uses a dual channel process to allow both the freedom to dynamically change channels as needed to avoid interference whilesimultaneously providing a capability to resynchronize any portable unit with the base unit on a selected active channel. This is achieved through the use of a fixed service channel and an active channel which changes as needed. If a channel change is made during a call, after the call is completed, the base unit returns to the previous active channel and broadcasts a message to the multiple portable units indicative of the new active channel. Also, any portable unit that attempts to communicate with the base unit on the wrong channel and fails to get a response will transmit a message on the fixed service channel requesting the current active channel from the base unit. Responsive to this request, the base unit provides information indicative of the active channel over the service channel. Once equipped with the current active channel information, the portable unit is able to reach and establish communications with the base unit.
